The feature still works for local files and images, but that data will no longer be synced across PCs. Starting with this release, Timeline will no longer sync activities across devices. One big change coming to 21H2 that some users may be effected by is with the Timeline feature, which can be found in the Task View button on the Taskbar.

GPU compute support in the Windows Subsystem for Linux (WSL) and Azure IoT Edge for Linux on Windows (EFLOW) deployments for machine learning and other compute intensive workflows.

Windows Hello for Business introduces a new deployment method called cloud trust to support simplified passwordless deployments and achieve a deploy-to-run state within a few minutes.

Added WPA3 H2E standards support for enhanced Wi-Fi security.

Here are the highlights for what's new in 21H2 for Windows 10: That likely means it'll be pushed out as an update for all in-support versions of Windows 10. Microsoft has already confirmed that the new Microsoft Store built for Windows 11 will also be coming to Windows 10 at some point as well, though this doesn't appear to be tied to a specific version of Windows 10. The user experience and feature set will remain mostly the same, which is good news for people who don't like change. This means that version 21H2 for Windows 10 doesn't include any notable changes that you'll have to adjust to. Just like 21H2 and 20H2 before it, version 21H2 for Windows 10 includes enterprise-grade enhancements and lots of fixes and under the hood improvements designed to make Windows 10 more stable to use day-to-day. Windows 10 version 21H2 does not include any new features in the traditional sense.
